A study has found that red wine’s impact on cancer risk is not significantly different from that of white wine.
The research results investigating the effects of both red and white wine on cancer occurrence were published in Nutrients.
While alcohol consumption is a known factor in cancer development, it has been unclear whether certain types of wine pose a greater risk than others.
Researchers from Brown and Harvard University analyzed 42 studies, including 22 case-control and 20 cohort studies, to investigate potential differences in the impact of red and white wine on cancer risk.
The overall findings indicated no significant difference in cancer risk between the two types of wine.
However, when examining only cohort studies, white wine appeared to increase cancer risk, while red wine showed no clear association.
The team also explored the relationship between alcohol consumption and cancer risk based on 3 cohort and 12 case-control studies.
For red wine, each additional daily glass (10g of ethanol) was associated with a 5% increase in cancer risk, while white wine showed no significant correlation.
Interestingly, the analysis revealed that white wine increased the risk of skin cancer by 22%. Both red and white wines were linked to higher breast cancer risk in women, with no significant difference between the two.
Based on these findings, the researchers concluded that there is no substantial difference in the overall impact of red and white wines on cancer risk.
